Unisource Style SF-TSC hose utilizes a very specialized construction to create a flexible connector suitable for the most severe applications.
Style SF-TSC is constructed using close-pitch, annually corrugated metal hose. A smooth-bore white PTFE liner is inserted into the hose and locked into place. Ends of the PTFE liner are flared over the stainless steel stub retainers that are welded to each end of the hose. This creates a hose connector with all wetted surfaces being PTFE. Floating flanges rotate behind the stub retainers.
Corrugated metal hose can be either T321 stainless steel (SF21-TSC) or T316 stainless steel (SF31-TSC). Standard single braid is made of T304 stainless steel. Special T316 stainless steel braid material is available on special order. Floating flanges do not contact the stream flow, and can be constucted of carbon steel, T304 or T316 stainless steel. Style SF-TSC hose is often used as a short connector between mechanical equipment or tanks and the solid piping system. They are often used to help reduce the effects of equipment induced noise, vibration, or shock, and offset movements caused by seismic activity or equipment settling. Style SF-TSC connectors provide high working pressures, superior corrosion resistance, moderate flexibility—even at elevated temperatures. The stainless steel convoluted outer hose of Style SF-TSC acts as a double containment device, and reduces opportunity for catastrophic failure and environmental releases. The PTFE tube is also cleanable under most common methods and is made of FDA approved materials, making the Style SF-TSC connector ideal in sanitary applications. While typical convoluted Teflon hose is only available in sizes up 3” or 4”, Style SF-TSC hose can easily be made in sizes as large as 12” diameter.
